THE PROBLEM
Head shaft is raised or lowered with the help of a
hydraulic system.
There is no indication for position of the head shaft and
the operator monitors the oil level in the hydraulic tank
to estimate position. This method is however error prone.
Head shaft is subjected to extreme pressure if raised or
lowered beyond limits, which may result into premature
failure.
A system to facilitate the operator to know the real-time
position of the head shaft is needed.
